Joel Henriques is an Oregonian who has given the the woodpecker lots of class and beauty. He makes things with his young twins. You can see his blog of amazing projects here or by clicking on the picture.

Why doesn't it drop or stop?

Here is yet another clever folk toy that uses science to puzzle and amaze observers. It uses it's potential energy to bob back and forth like a woodpecker. It was redesigned a bit so that even young kids can help make it. The classic version usually uses a tiny spring--as from a pen--but we simply use a rubber band for springyness.
